This file is just a placeholder, since this is the "unstable" branch -of Redis, the place where all the development happens. +================================================================================ +Redis 7.0 RC1 Released Mon Jan 31 12:00:00 IST 2022 +================================================================================ -There is no release notes for this branch, it gets forked into another branch -every time there is a partial feature freeze in order to eventually create -a new stable release. +Upgrade urgency LOW: This is the first Release Candidate of Redis 7.0. -Usually "unstable" is stable enough for you to use it in development environments -however you should never use it in production environments. It is possible -to download the latest stable release here: +Redis Release Candidate (RC) versions are early versions that are made available +for early adopters in the community to test them. We do not consider +them suitable for production environments. - http://download.redis.io/releases/redis-stable.tar.gz +Introduction to the Redis 7.0 release +===================================== -More information is available at https://redis.io +Redis 7.0 includes several new user-facing features, significant performance +optimizations, and many other improvements. It also includes changes that +potentially break backwards compatibility with older versions. We urge users to +review the release notes carefully before upgrading. + +In particular, users should be aware of the following changes: + +1. Redis 7 stores AOF as multiple files in a folder; see Multi-Part AOF below. +2. Redis 7 uses a new version 10 format for RDB files, which is incompatible + with older versions. +3. Redis 7 converts ziplist encoded keys to listpacks on the fly when loading + an older RDB format. Conversion applies to loading a file from disk or + replicating from a Redis master and will slightly increase loading time. +4. See sections about breaking changes mentioned below. + +Here is a comprehensive list of changes in this release compared to 6.2.6. +Each one includes the PR number that added it so that you can get more details +at https://github.com/redis/redis/pull/<number> + +New Features +============ + +* Redis Functions: A new way to extend Redis with server-side scripts (#8693) + see https://redis.io/topics/functions-intro +* ACL: Fine-grained key-based permissions and allow users to support multiple + sets of command rules with selectors (#9974) + see https://redis.io/topics/acl#key-permissions and https://redis.io/topics/acl#selectors. +* Cluster: Sharded (node-specific) Pub/Sub support (#8621) + see https://redis.io/topics/pubsub#sharded-pubsub +* First-class handling of sub-commands in most contexts (affecting ACL + categories, INFO commandstats, etc.) (#9504, #10147) +* Command metadata and documentation (#10104) + see https://redis.io/commands/command-docs, https://redis.io/topics/command-tips +* Command key-specs.
